IMPROVEMENT m BEER-FAUCETS.

Specification forming part of Letters Patent No. 179,050, dated J one 20, 1876 application filed May 11, 1876.

To all whom it may concern:

Be it known that I, THOMAS C. PERKINS, of Brighton, in the county of Sacramento and State of California, have invented a new and valuable Improvement in Beer-Faucets; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being bad to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure l of the drawings is a representation of a vertical central longitudinal section of my invention. Fig. 2 is a side view of the faucet-section of the coupling-plug. Fig. 3 is a transverse section of the plug and bushing through the coupling. Figs. 4 and 5 are views of the bushing and its plug-section.

This invention has relation to faucets for beer-kegs and other purposes; and it consists in the construction and novel arrangement of the threaded bushing, having countersunk margins to its bore, and the threaded coupling-plugs, provided with beveled valve-shoulders, to engage with the countersunk margins of the bushing, and respectively designed tov be inserted into the keg, and connected with the faucet-spout, as hereinafter fullyrshowu and described.

In the accompanying drawings, the letter A designates the wall of a keg or barrel, into which the plug isinserted. B represents the bushing, which is designed to be screwed into the opening a, and is provided with an external thread, I), for this purpose. The bore of the bushing is also threaded for a certain distance, as shown at c, a portion thereof adjacent to the front opening being reamed out of larger diameter than the threaded part, as shown at d, the two parts being separated by an-internal shoulder, e. The front end of the bushing is provided with a heavy flanged key.- seat, f, so that it can be readily screwed into At each end of the bore an internally-beveled or countersunk margin or seat, n, is provided, to engage with the valve-shoulders of the plug-sections. 0 rep resents the interior plug section, which is screwed into the rear end of the bushing, being provided with an external thread, g, for

that purpose. This thread is separated near its rear end into two portionsby a smooth space, h, where the inlet perforations k are located. The front end of this section is provided with opposite projecting lugs Z, being quadrant-sectors in cross'section, cut away centrally by the bore. The rear end of the section is provided with a flange, m, which is separated from'the threaded surface by the beveled valve-shoulder e, which, when this section is screwed home, is designed to engage with the marginal-valve-seat of the bushing. This section should be screwed into the bushing before the latter is introduced into the keg. D indicates the exteriorsection of the coupling-plug, consisting of a large threaded cylindrical portion, 12, and a smaller portion, q, also threaded, and separated from the larger portion by a beveled shoulder-valve, v. The rear end of this section is provided with quadrant-lugs, similar to those of the front end of the interior section, between which they are introduced into the reamedout portion of the bore of the bushing, when it is desired to attach the faucet thereto. F representsthe faucet, which may be of any size. The rear end 1' of its stem should be reamed out and threaded interiorly, to receive and engage with the larger threaded end of the plug-section D, which, when screwed home therein, should have its valve-shoulder v slightly projecting. The lugs of this section serve as a key-seat to force it into the faucet-stem. I

As stated above, when the bushing is introduced into the keg, the plug-section O is already therein screwed home, sothat its inlet perforations are covered by the wall of the bushing, and its valve-shoulder is closely engaged with the beveled marginal seat a at the rear end of the bore of the bushing. These two pieces are designed to remain permanently attached to the keg.

When a faucet is to be used it is connected to section 0 by the intermediate section D. This section is screwed home in the stem of the faucet, and its bifurcated end is introduced into the reamed-out chamber 61 of the bushing between the lugs of section 0. Then, by turning the faucet, the coupled sections will move rearwardly in the bushing'until the inlet perfor-ations of section 0 are uncovered, and the valve-shoulder of section D is engaged with the countersunk seat n in the front end of the bushing, forming a tightjoint. If the bushing has been properly set by gaging it with a faucet, the spout will always be down when the engagement is made between the marginal seat of the bushing and the valve-shoulder ot' the faucet-plug section. Communication is thus readily established with the faucet. In like manner any faucet may be applied, pro' "ided its stem is threaded to receive the section D; or the same faucet and section D may serve for several kegs, having the bushing in each, with section 0 engaged therein.

What I claim as new, and desire to secure by Letters Patent, is-

The combination, with a faucet, F, having the threaded end 1', of the threaded bushing 13, having the reamed chamber d, and the beveled marginal valve-seats n at the ends of its bore, and the interlocking plugs O D, respectively provided with the rear enlargement m and the threaded front enlar'gemeut 19, having beveled shoulders 'v c, said plugs being
